6o REPORT OF NEW JERSEY STATE MUSEUM. 

 Erom the above list we may compute : 



Total Flora of Pine Barrens, 



" " " Coast Strip (excluding Halophytes),. 



" " " Cape May District, 



" Middle District, 



Common to Middle and Pine Barren Districts, 



" " Coast Districts, 



" " Cape May Districts, 



Pine Barren and Coast Districts, 



" " Cape May Districts, 



Coast and Cape May Districts, 



The status of each species in the above table was ascertained 

 by a careful study of the data presented in the main text of this 

 report after excluding such records as bore evidence of being 

 based upon accidental occurrences such as roadside or railroad 

 introductions. All weeds, even those of native origin, were also 

 excluded, as their distribution has little or no bearing upon 

 natural conditions. 



A further study of the data covering the general range of 

 the south Jersey plants (see p. 47) gives the following results 

 for the flora of each of the four districts considered separately : 



Wide Ranging, 628 



Northern Element, 78 



Southern Element, 299 



Local Element, 18

* As explained beyond, these figures include a number of recent introduc- 

 tions not really native to the Pine Barrens. See p. loi. 



t These figures are somewhat misleading, as only such Pine Barren species 

 as reach the Coast Islands are included. The mainland coast strip is so 

 narrow that it is impossible to mark it off sharply from the Pine Barrens, 

 and we cannot sr,y which Pine Barren species spread into it and which do 

 not, without a vast amount of further study.
